Data caps protect incumbent big studio and network content creators at the expense of independent producers and others challenging conventional entertainment business models.

That was the conclusion of several writers and producers at a communications policy forum hosted by Public Knowledge, a consumer group fighting for an open Internet.

A representative from the Writers Guild of America West noted that cord-cutting paid cable TV service has become real and measurable because consumers have a robust online viewing alternative for the first time. John Vezina, the Guild’s political director, noted how Americans watch television is transitioning towards on-demand viewing.

New types of short-form programming and commissioned series for online content providers like Netflix are also changing the video entertainment model.

Welch: It is about the money.

But a digital roadblock erected by some of the nation’s largest broadband providers is interfering with that viewing shift: the data cap.

Data caps place artificial limits on how much a customer can use their Internet connection without either being shut off or finding overlimit fees attached to their monthly bill. Critics contend usage caps and consumption billing discourage online viewing — one of the most bandwidth intensive applications on the Internet. With broadband providers like Time Warner Cable, AT&T, Verizon, and Comcast also in the business of selling television packages, cord-cutting can directly impact providers’ bottom lines.

Providers have traditionally claimed that usage limits are about preserving network resources and fairness to other customers. But Time Warner Cable admits they exist as a money-making scheme.

Rachel Welch, vice president of federal legislative affairs at Time Warner Cable, says the cable company is not worried about limiting data consumption. It considers monetizing that consumption more important.

“We want our customers to buy as much of the product as possible,” Welch told PC World. “The goal of companies is to make money.”

Time Warner now offers customers a choice of unlimited service or a $5 discount if customers keep their monthly usage under 5GB, but some worry that is only a prelude to introducing expanded usage limits on a larger number of customers in the future.

For many consumers already hard-pressed by high broadband bills, worrying about exceeding a data allowance and paying even more may keep viewers from watching too much content online.

For that reason, Vezina called data caps “anti-innovation.”

“It hurts consumers [and] it hurts creators who want to get as much out to the public in as many ways” as possible, he said.

Public Knowledge has become increasingly critical of data caps in the last two years. The organization has questioned how ISP’s decide what constitutes a ‘fair’ usage limit and criticized inaccurate usage meters that could potentially trigger penalties and overlimit fees.
